Pinpoint Tests P: Fuel Injector: Introduction

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, 2016 Ford Transit-150, and 2016 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: CONTACT WITH EXPOSED FUEL INJECTOR WIRING, IF ENERGIZED, MAY RESULT IN ELECTRIC SHOCK. USE CARE WHEN WORKING ON OR AROUND ENERGIZED FUEL INJECTOR WIRING. FUEL INJECTOR WIRING SUPPLIES HIGH VOLTAGE TO OPERATE THE FUEL INJECTORS. FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN SERIOUS PERSONAL INJURY.

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

This pinpoint test is intended to diagnose the following:
